SPRINKLING-PIPE.

I Specification of Letters latent.

Patented Dec. 13, 1910.

To all whom it may concern:

Be it known that I, OLIVER JEFFERSON Knrmnnig-a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have 1nvented certain neua and useful Improvements in sprinkling-Pipes, of which the following is a specification.

This invention relates to new and useful improvements in water'pipes.

The object of my invention is to provide a sprinkling pipe, having a plurality of discharge openings, each containing a sprinkling nipple so arranged as to be practically proof against'elogging by corrosion.

'Another object 1s to provide a sprinkling pipe with a plurality of non-corroding nipples which are driven into and artly through a tapering opening to protru e into the pipe a comparatively short distance.

A still further object is to provide a sprinkling pipe with a nipple of compressible metal which is driven under force into and partly through a slightly tapering seat so that the protruding ends of the nipples will expand after protrusion to securely hold the nipple to its seat.

lVith these and other objects in view, the

,present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and particularly pointed out in the appended claim, it being understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of theinvention.

In the drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view of a pipe constructed according to my invention. Fig. 2 is a longitudinalsectlonal view,

My present invention rovides a sprinkling pipe so constructed that the sprinkling nipples will be practically proof against corrosion.

As clearly shown in the drawings the pipe 10 represents an ordinary water pipe of any suitable length and diameter, provided along its length with a plurality of slightly tapering openings 11, leading from the outer periphery of said pipe with their smallest diameters on a line with the inner surface of the pipe. Held within each conical seat 11 is a plug 12, made of some non-corroding compressible metal, and these plugs are driven under force into the tapered seats so pipe a suitable distance, as shown in the drawings. As theplug is carried -through the seat in a compressed condition, as soon as the inner end protrudes beyond the seat opening the metal expands to'a certain degree, so thatthe plug is firmly held to its seat. The outer end of the plug is flush with the outer surface of the pipe andconforms to the surface of the same. After the plugs have been properlv positioned they areprovided with the centrally located bore 13, as shown. As the inner end of the a considerable distance, the corrosion "or scale forming upon the inner surface of the pipe can in no wayinterfere with the'free 13. The plugs referred to are ofgreater same. After being seated these plugs form nipples through which the water is discharged. 'The openiugs.13, within the plugs 12, may extend at'any desired angle to the axes o the plugs.

In carrying out my,invention I employ a metal having the properties of compressi ,bility, elasticity, and non-corrodibility, such that their inner ends will protrude into the,

discharge ofthe water through the opening nipple-formingplug projects into the pipe 1 diameter than the seat'for receiving the transverse sectional view of one of the nipas brass, copper or'lead 0r a composition of ple's. t As water pipe 15- usually made of 1ron,

-' and as thti'pipe 1s subject to corrosion and .i in

will further become incrusted, it is quite not become clogged. And having thus such metals, whereby the apparatus l3 will described my said insecure United States Letters Patent is:

.lventioug'v vhat I claim .as-new and desireto it A sprinkling pipe provided withaslightlyapering opening leadin from theouter J periphery of the'same w th its srnalllest' di- Within the pipe, said plug having a central bore, as and far the put ose descnbed. 10

In testimony whereo I affix my signature, in presence of two Witnesses.
